Load testing and MyEd

One disappointment in the run-up to the new semester was that the upgrade to our university portal failed its load test.  In other words, when we tried running ithe new version with automated tests that simulated the number of staff and students who would be using it in real life, the time it took to display the login screen was too long to be acceptable. Hence we decided to delay the upgrade.

The good news is that we have found the cause of the problem and we have a fix. So we should be able to give staff and students the enhanced version sometime around the middle of the semester. 

An underlying point is that these tests are an important part of our quality assurance process. The portal is used every day by thousands of people and the poor performance we were seeing would have significantly affected their work.  We can take some satisfaction from the fact that we did catch the problem before putting the new system live.

Ideally we would have run the load tests earlier so that we would have had time to fix the problems and still deploy the new version on schedule.  Unfortunately this was not the first stumbling block that we encountered with this upgrade.  Some projects are like that.  It's not unusual to find some problems on any project - in fact it would be most unusual to have none at all - but there are some projects that seem to attract more than their fair share.

We will have a review of the project when is finally completed, with the aim of looking for ways of avoiding problems in future projects.  For example, one issue that we have already noted is that the way the portal technology handles groups of users is changing, and this change does seem to be related to the performance problems we were seeing.  This suggests that we will have to change our implementation to match the new way of working, next time we upgrade this technology.

2016 has been a good year

So much has happened over the last year with our Enterprise Architecture practice that it's hard to write a succinct summary.  For my day-to-day experience as enterprise architect, the biggest change is that I now have a team to work with.  This time last year, I was in the middle of a 12-month secondment to create the EA practice, working mainly on my own.  Now my post has been made permanent and I have recruited two members of staff to help meet the University's architectural needs.

I have spent a lot of the year meeting people, listening to their concerns and explaining how architecture can help them.  This communication remains vital, the absolute core of what we do and we will continue to meet people in this way.  We also talk to people in other Universities in order to learn from what they are doing and to share our own experience back.  A highlight in this regard was my trip to the USA last January.

Our biggest deliverable for the past year was the design of the data wa…

A new EA Repository

One of my goals since starting this job two years ago has always been to create a repository for architecture documents.  The idea is to have a central store where people can find information about the University's applications, data sources, business processes, and other architectural information.  This store will make it easier for us to explain our plans, to show the current state of the University's information systems, and to explain what Enterprise Architecture is all about.

It's taken a long time to reach this goal, mainly because we're often had more pressing and immediate work to be done.  The creation of a repository is one of those tasks that is very important but never quite urgent.  So I'm now very happy to say that we are in the process of deploying a repository and modelling tool.


This is the culmination of a careful process to select the most appropriate tool for our needs.  We began by organising several workshops to gather requirements from a rang…

New staff for the EA team

I'm delighted to welcome Jason Murphy, who joins us as our CRM Architect, and Wilbert Kraan, our new Data Architect.  Both Jason and Wilbert have worked as consultants for several years and bring new skills and considerable experience to IS.  They both know more than I do about their respective fields, which is how I like to hire people.

So the Enterprise Architecture practice now comprises the three of us, instead of me working on my won, which means we have more capacty to guide the University's IT architecture.  We can offer a greater range of skills and can bring a wider range of experience to bear.  I'm really excited about the opportunities this presents.

As his job title implies, Jason will focus on contact relationship management, working to build a user community and to create a strategy for managing and improving the University's relationships with prospective students, research partners, community organisations, and other parties - to give them all a better …
